Immediately after taking the final quiz from Math Challenge 1-B (AMC 8/ Mathcounts), I got a screen showing my score that said I got a 75 and had 5 problems wrong.  Then I clicked on my class, but it said coding error. So I re logged. But, when I logged out and later logged back in to review my problems, it said I got a 60 with 8 problems wrong, with some problems blank. Did anyone else have this problem...?

*If someone could maybe fix this or help find out why this happened, it would be highly appreciated :)
